Before Lunar New Year, I had ordered two 3000 F, 2.7 V supercapacitors from China for about $4 each. I don’t actually remember why, but they arrived (unexpectedly) just before the holiday.

Milpitas, Calif.&#8212Linear Technology's LT3485 family integrates a complete photoflash capacitor charger, IGBT drive stage, and output voltage monitor in a 3-by-3 mm DFN package. The chip's control ...

Because their voltage ratings are low, ultra-capacitor cells are frequently combined into modules or packs where they are series connected to handle higher voltages. However, ultracapacitor ...

A capacitor charging power supply has two power ratings expressed in Joules per second (J/s), the peak power and the average power. The peak power rating is used when calculating the charge time, and ...

(Nanowerk Spotlight) Low energy density is a main challenge for batteries and capacitors. Researchers are constantly developing new materials to increase the energy density of electrochemical energy ...

Smartphones are some of the most useful devices we own. However, their battery life leaves a lot to be desired. Even the most power frugal devices need to be charged daily during heavy use - something ...
